[0022] The cooling assembly 5 includes a servo motor A51 fixedly mounted on the right side near the top of the drill body 2 and a turntable 52 fixedly mounted on the output end of the servo motor A51. A fixed shaft 53 is fixedly mounted on the right side near the front of the turntable 52, and a sliding frame 54 is slidably sleeved on the outer side of the fixed shaft 53. A connecting plate 55 is provided below the bottom of the sliding frame 54. An annular nozzle 56 is fixedly mounted on the left side of the connecting plate 55. The annular nozzle 56 is movably sleeved on the drill housing on the drill body 2. A connecting pipe is fixedly installed through the middle of the rear side of 56. A hose 57 is fixedly installed at the lower end of the connecting pipe. A connecting pipe is fixedly installed at the lower end of the hose 57. A suction pump 58 is fixedly installed near the bottom on the right side of the coolant tank 6. The top of the suction pump 58 is fixedly connected to the lower end of the connecting pipe. A suction pipe is fixedly installed on the front side of the suction pump 58. The front end of the suction pipe extends through the inner cavity of the coolant tank 6. It can spray coolant to cool the drill bit and remove debris to prevent it from adhering to the drill bit.

[0023] Several spray heads 561 are fixedly installed at equal intervals at the bottom of the annular nozzle 56, which facilitates the spraying of coolant and can spray the drill bit.

[0024] Vertical rods 541 are fixedly installed at the bottom of the sliding frame 54 near the front and rear sides, and the lower ends of the vertical rods 541 are fixedly installed on the connecting plate 55. This allows the connecting plate 55 to move up and down synchronously with the sliding frame 54, thereby adjusting the height of the spray head 561, which helps to increase the spraying range and avoid certain limitations.

[0025] Two limiting telescopic rods 551 are fixedly installed on the top of the connecting plate 55 near the left side, and the limiting telescopic rods 551 are arranged front and rear. A flat plate 552 is fixedly installed on the top of each limiting telescopic rod 551. An L-shaped plate 553 is fixedly installed on the left side of the flat plate 552. The left side of the L-shaped plate 553 is fixedly installed on the drilling machine body 2, which serves to guide and limit the movement of the connecting plate 55, so that it can move up and down stably.

[0026] The positioning component 4 includes a placement frame 41 fixedly installed at the top center of the workbench 3. Vertical plates 42 are provided on both the front and rear sides of the placement frame 41. The bottom of the vertical plates 42 is fixedly installed on the workbench 3. A hydraulic push rod 43 is fixedly installed through the vertical plate 42 near the top. A positioning plate 44 is fixedly installed on the power end of the hydraulic push rod 43, which serves to clamp and fix the workpiece to be processed, and has high stability.

[0027] The coolant tank 6 has chip collection ports 61 on both the front and rear sides near the top, and chip collection tanks 62 are fixedly installed on both the front and rear sides near the top. The coolant tank 6 has a movable port 63 on the left side near the top, which facilitates the discharge and collection of debris.

[0028] In this embodiment: During use, the operator can place the workpiece on the placement frame 41. After placement, the hydraulic push rods 43 on both sides can be activated. The operation of the hydraulic push rods 43 will drive the adjacent positioning plates 44 to move relative to each other, thereby clamping and fixing the workpiece. After clamping and fixing, the drilling machine body 2 can be activated to drill the workpiece. During processing, the suction pump 58 can be activated to draw coolant from the coolant tank 6 and deliver it to the annular nozzle 56 through the connecting pipe, hose 57 and connecting pipe. Then, the nozzle 561 sprays the drilling machine body to cool it down, preventing the high temperature generated during drilling from affecting the service life of the drilling machine body. At the same time, it can also remove debris attached to the drilling machine body. The debris is sprayed down, allowing impurities to enter the coolant tank 6 along with the coolant. The filter screen 7 filters out the impurities in the coolant, leaving them on the filter screen 7, thus recovering the coolant. In addition, the height of the spray head 561 can be adjusted according to actual needs during spraying. The operation of the servo motor A51 drives the turntable 52 to rotate. When the turntable 52 rotates, it drives the sliding frame 54 to move up and down through the fixed shaft 53. When the sliding frame 54 moves up and down, it drives the connecting plate 55 to move up and down through the vertical rod 541, which in turn drives the annular spray pipe 56 to move, thereby adjusting the height of the spray head 561. After adjustment, the servo motor A51 can be stopped.

[0029] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 , Figure 3-6 and Figure 8 The cleaning component 8 includes two side plates 81 fixedly installed on the left side of the coolant tank 6 near the top. The side plates 81 are arranged front and back, and a threaded rod 82 is provided on the opposite side of the side plates 81. The rear end of the threaded rod 82 is movably installed on the rear side plate 81, and the front end of the threaded rod 82 extends through to the outside of the front side plate 81. A servo motor B83 is provided on the front side of the front side plate 81. The output end of the servo motor B83 is fixedly connected to the front end of the threaded rod 82. A threaded sleeve 84 is threadedly installed on the outside of the threaded rod 82 near the front end. A scraper 85 is attached to the top of the filter screen plate 7 near the front side. The scraper 85 can be driven to move back and forth left and right to scrape and clean the impurities on the filter screen plate 7 into the chip collection grooves 62 on both sides.

[0030] An L-shaped support plate 831 is fixedly mounted on the front side of the servo motor B83, and the rear side of the L-shaped support plate 831 is fixedly mounted on the front side plate 81, which serves to support and fix the servo motor B83.

[0031] A guide plate 841 is fixedly installed at the middle of the bottom of the threaded sleeve 84, and a guide rod 842 is slidably installed through the guide plate 841. Fixing plates 843 are fixedly installed at both ends of the guide rod 842. The top of the fixing plates 843 is fixedly installed on the adjacent side plates 81, which serves to guide and limit the movement of the threaded sleeve 84, resulting in high stability.

[0032] An L-shaped fixing rod 851 is fixedly installed on the left side of the scraper 85 near the top. The end of the L-shaped fixing rod 851 away from the scraper 85 passes through the inner cavity of the moving port 63 and is fixedly installed on the threaded sleeve 84. This allows the scraper 85 to move synchronously with the threaded sleeve 84, which is beneficial for the scraping and cleaning work.

[0033] In this embodiment: when the coolant spraying begins, the servo motor B83 can be started. When the servo motor B83 is running, it will drive the threaded rod 82 to rotate. When the threaded rod 82 rotates, it will drive the threaded sleeve 84 to move back and forth. When the threaded sleeve 84 moves back and forth, it will drive the scraper 85 to scrape and clean the filter screen plate 7 from side to side through the L-shaped fixing rod 851. Impurities on the filter screen plate 7 can be pushed to the chip collection groove 62 through the chip collection ports 61 on both sides for collection, so as to avoid impurities accumulating on the filter screen plate 7 and thus affecting the efficiency of coolant filtration.
